You will enjoy this movie if you step back and watch it like a spoof put together by the actors themselves. Otherwise the story as portrayed in this production is just not logical. There are irritating loose ends and tangents that I found frustrating. However they are all great actors doing a fine job and if you take it as it comes and just accept it as a silly spoof then you will enjoy it. Why an otherwise sensible, financially independent, elderly widower, would move in with an old grumpy, ungrateful, insulting, rake is not well explained. If you are going to write a script at least give good solid logical reasons to support why a character follows a particular course of action. The moment I gave up asking why so and so did such and such I began to enjoy the journey. A few drinks would also help. It is a silly movie that I ended up enjoying. Rosamund Pike - her movie debut - and some others appear for about half a second. One wonders why you would go to the trouble of assembling a cast of actors who may well spend three days on set only to be almost invisible in the final production. Even more outrageous is that very often, some bugger would have spent weeks mulling over who to cast in these invisible roles. We can only hope the invisible ones receive regular residuals ! So grab a stiff drink, relax, throw logic out the window and watch this movie.
